I! b all whom it may concern:

Be it known that I, ARTHUR L. BURTON, a citizen of the United States, residing at Fairhaven, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Bobbin-Cleaning Machines, of which the follow ing is a specification, reference being had to the accompanying drawings. p

This invention relates to devices for stripping or cleaning bobbins such as are used in the operations of spinning, doubling, twisting, roving, or other spooling opera tions, and the general object of the invention is to provide very simple and eficient means whereby the tail ends or unused portions of the yarns or rovings remaining on i spent bobbins may be stripped from the bobbins at small cost, with rapidity, and without the necessity of using skilled labor.

A further objectis to provide a construction of this character which requires very little power to run it, and which includes a rotatable stripping element having thereon an outer sheet or covering formed of card,

clothing.

A further object is to provide a device of this character including a table, a rotatable stripping element, a guard housing normally partially inclosing the stripplng element but having an opening through which the SlZI'lP-', ping element slightly pro ects, and ftClJHStable means for preventing the bobbin from being injured by thecard clothlng.

A further object is to provide for the ready removal or replacement of the rotatable element, and provide a compartment into which the strip waste from the combination is discharged.

Other objects will appear in the course of the following description. p

My invention is illustrated 1n the accom panying drawings, wherein 2- Figural is a perspective view of a bobbin cleaning machine constructed in accordance with my invention;

Fig. 2 is a vertical sectional view through one of the housings and the cleaning roller showing the manner in which the machme is used;

Fig. 3 is a sectional view through the housing and table showing the roller 1n elevation;

Fig. i is a fragmentary perspective view showing the manner in which the housing turns back upon the table to expose the cleaning roller; and

cleaning element. ing is applled to the rotatable element in any Fig. 5 is a side view of a portion of the card clothing used on the roller.

Referring to the drawings, 10 designates a table which may have any required length and which is supported at intervals by legs 11. This table is shown as supporting two bobbin cleaning devices. This, of course, is not an essential part of the invention. lt0- tatably mounted above the table are one or more rotatable cleaning members 12, each having a shaft 13, the shaft being shown as provided with fast and loose pulleys engaged by a belt 14: which passes from a driv ing or counter-shaft, means being provide-d whereby thebelt may be shifted from the loose to the fast pulley and vice versa.

The rota-table element is cylindrical in form and made of any suitablematerial, but is covered upon its exterior face with a fillet of card clothmg 15 havlng, as usual, very fine teeth projecting from its surface. Preferably, this strip of card clothing is taken from cards which are too much worn to be used for their original purpose, which card clothing would ordinarily be destroyed. l have found, however, that in actual practic these pieces of worn card clothing may be used, and preferably will be used upon the This fillet of card clothdesired way so that it may be removed and replaced with a new fillet whenever necessary.

Hingedly mounted upon the table 10 is a housing 16 consisting of end members, and side members 17, the side members being preferably disposed indownwardly diverg ent relation, and one of these side members being hinged to the table by the hinges 18.

On each side member 17 thcreis provided. a vert cally movable sl1de 19 moving between guldes 20 and having a vertlcally ex tending slot 21 through which passes a bolt having a wing nut 22. The slide may thus be adjusted vertically and then clamped in its adjusted position. Both of these slides will be adjusted alike. A housing comprising a back board 23, a top board 24, and end members 25 will extend over each cleaning device at a suflicient distance to give an operator plenty of room, and rearward of the cleaning roller this housing will be provided with a door 26 so as to form a partially open compartment rearward of the cleaning device into which the fly waste will be discharged, as illustrated in Fig. 2.

Receptacles for holding the cleaned bobbins may be disposed beneath the table 10 so that the bobbins can be dropped therein by the operator as soon as cleaned.

In the operation of this device, the slides 19 are so set that the bobbin when disposed upon the upper edge of the slide will have the waste thereon engaged by the card clothing of the cleaning element,'but preventing the bobbin itself being brought into contact with the card clothing and thus injured. Trucks or receptacles containing bobbins to be cleaned are disposed near the left hand of the operator and the operator picks up a handful of the bobbins and with his right hand passes one,'tw0, or three bobbins at a time over the top of the guard box or housing 17, resting the bobbins uponthe upper edges of the slides, and the rapidly rotating card clothing cleanses the bobbins. The cleaned bobbins are then dropped into-the receptacles below the table.

It will be seen thatiny machine requires noskilled-labor in order to operate it, and that an entirely ignorant person can operate the machine veii iciently with no instructions at all. It has been found in practice that this device will clean nine thousand bobbins a day at each unit of cleaning cylinder, or eighteen thousand bobbins a day on the complete two-unit machine. This has been done with unskilled labor working seven hours out of an eight-hour day.

The cleaning device will not damage bobbins and the tail ends or unused portions of yarn or roving remaining on the spent bobbins, after bein -cleaned from the bobbins, is in as good or better condition for remixing with the regular yarn than the waste from any other bobbin cleaning ma-- chine known to me. There are no parts to repair outside of renewing the card clothing on the rotatable cleaner and itdoes not require skilled labor in order to renew these rds It will be understood that after passing the bobbins over the rapidly revolving card clothing, the operator holds the bobbins over the waste cans which are disposed beneath the table 10 and merely slides the waste oil the bobbins with the tips of his fingers on the left hand. This roving waste is not thrown completelyaway by the card clothing and thrown into the compartment behind the door 26, and nothing but loose fly waste goes intothe space behind these doors 26, but the real roving-waste is deposited in the cans or other receptacles disposed beneath the tables, the discharge of this roving waste being indicated in Fig. 2.

I am aware that automatic bobbin cleaning machines have been proposed, but all of these machines required skilled labor to 01)- erate and they are suiiiciently delicate in structure to readily get out of order and require expensive repairs to be made. I am also aware that bobbins have been cleaned by means of card clothing, but in this case a strip of card clothing has been tacked to a piece of wood and the bobbin has been scraped by hand against the card clothing to remove the waste. This is a long and tedious operation. In actual operation the cleaning roller 12 should be rotated at a speed of 1200 R. P. M. and of 1 H. I. is required for each unit of two cleaners.

While I have illustrated certain details of construction and arrangement of parts, which I have found to be thoroughly effective in actual practice, yet I do not wish to be limited to this, as it is obvious that many changes might be made in the details of construction and arrangement of parts without departing from the spirit of the invention.
